Title: Solid electrolyte for secondary battery and manufacture thereof
Inventor: NISHIMURA MAKOTO
IPC: H01M10/39
Filed: 1989-09-01
Abstract: PURPOSE:To improve the strength of a solid electrolyte by depositing an amorphous material containing SiO2 on a ceramic crystal grain boundary, and giving Na ion conductivity to the amorphous material. CONSTITUTION:A solid electrolyte for a secondary battery is made of ceramic C mainly constituted of either one of beta-alumina, beta''-alumina and a mixture of beta-alumina and beta''-alumina. The solid electrolyte for the secondary battery is deposited with an amorphous material containing SiO2 on the crystal grain boundary of ceramic C, and this amorphous material has Na ion conductivity. The ion conduction resistance of ceramic C is not increased, Na ions pass the amorphous material and are moved to adjacent crystal grains even if Na ion conduction faces of crystal grain boundaries differ, thus no Na is deposited on the grain boundary. The strength of the solid electrolyte is improved.

Abstract: PURPOSE:To produce a signal which has large and short cycles at low and high temperatures respectively in a semiconductor device, by making use of a phenomenon where the electric charge stored in an electrostatic capacity is discharged as a leakage current to decide the cycle of a timer circuit. CONSTITUTION:An electrostatic capacity CR1 is charged through a transistor TRD1; while an electrostatic capacity CR2 is charged through a TRD2 respectively. Under such conditions, a signal phiP is set at a low level to start a timer circuit. The electric charge of capactities CR1 and CR2 are reduced by the leakage as the time elapses and then chaged throgh the TRD1 and D2 when the levels of nodes B1 and B2 are reduced.

Title: Deflection high tension supply circuit of ink jet printer
Inventor: ISHIMA KAZUMI
IPC: B41J2/09
Filed: 1985-10-09
Abstract: PURPOSE:To stabilize an output voltage of a deflection high-tension supply circuit under a simple circuit configuration by holding the input pulse of a buffer circuit provided on the input side of a piezoelectric transformer at a constant voltage level. CONSTITUTION:A transistor Tr is provided as a buffer. An input pulse Pf is accompanied by a voltage variation; however, this variation does not appear at A point because the transistor Tr performs a switching operation. However, it is common that the variation amounts to a few percent normally although the +DC voltage is stable. Therefore, unless a Zener diode ZD is provided, the variation appears at A point and is multiplied proportionately to the boosting of a piezoelectric transformer T. For this reason, the variation cannot be ignored. The Zener diode used should preferably be such as one for reference voltage with a temperature compensation. A voltage stabilized by the Zener diode is applied to the piezoelectric transformer T to assure satisfactory temperature characteristics of the transformer, so that a constant high tension is obtained in HV0.

Filed: 1990-08-28
Abstract: PURPOSE:To surely attain the hardware break even in a burst transfer mode by providing a 1st and a 2nd comparators, a magnitude comparator, a multiplexer, and a gate. CONSTITUTION:The comparator 21 detects the equal comparison between a part I excluding a part IIB equivalent to the burst transfer size and the part where a word size is designated within an address received from a CPU 1 and the value A in an address register 3. The comparator 22 detects the equal comparison between the part IIB and the value A. A magnitude comparator 23 outputs a detection signal when A>=B is satisfied. A multiplexer 4 selects the output of the comparator 23 at reception of a burst mode signal B and selects the output of the comparator 22 in a mode except the burst mode respectively. Then a gate 5 applies an interruption to the CPU 1 when both inputs are 'true' at one time. As a result, the hardware break is attained even in a burst transfer mode.

Title: Improved logic circuit
Inventor: RODONII JIEEMUSU ROOSON
IPC: H03K19/018
Filed: 1988-09-09
Abstract: PURPOSE: To obtain a large drive capability with small power consumption by providing a couple of transistor(TR) pairs and a switching means used to minimize a voltage difference on each emitter. CONSTITUTION: Two emitter follower TRs Q1 , Q2 form a drive stage of an ECL circuit. An emitter voltage of the TR Q1 is close to an ideal response of an output TR following with fidelity to an input voltage applied to an input terminal 10. The emitter of the TR Q2 receives the same input voltage and receives the effect of a capacitive load and a voltage across the capacitor C1 changes more slowly as the capacitor is charged/discharged. When the voltages above are fed to a differential amplifier 12, the amplifier output operates a current controller so that the emitter voltage of the TRQ2 follows to the emitter voltage of the TRQ1 with fidelity. A TRQ3 acting like the current controller is switched on to discharge the capacitor C1 when the emitter voltage of the TRQ2 is too high. Thus, the amplifier 12 switches off strongly the TRQ3 when the emitter voltage of the TRQ2 is low.
